lb all "Lu/tom it may ooncmw:

Be it known that I, HENRY KING,OfSt. Leon ards-on-Sea, in the county of Sussex, England, have invented a new and useful Improvement in Time-Indicating Devices; and I do hereby declare the following to be a full, clear, and exact description of the same.

This invention relates to ti hie-indicating devices, and has for its object the arrangement and construction of a simple mechanism whereby a clock or timepiece is adapted to indicate on a separate dial or dials or face or faces provided with hands or other indicators the time or the sum of the times occupied by a certain operation or series of operations, the mechanism being so arranged as to enable any dial or face to be immediately connected with or disconnected from the clock or timepiece at the will of the operator.

This device is particularly applicable for indicating the periods of time occupied by two or more opponents or competitors at a game of chess or at any other trial of skill, of work, or of endurance. It is obvious, however, that it may be used for many other purposes-such as, for example, indicating the time occupied by any piece of work, whether performed at one time or in several portions, or the time during which a messenger is engaged on his commission.

To carry my invention into effect, I take any ordinary clock or timepiece, and I attach to it externally a cog-wheel, wheel, or other gear connected with the minute or hour hand mechanism. I mount upon a board, plate, or other support a dial or face or a series of dials or faces having time-divisions, and to each dial or face I arrange a hand or hands or index driven by a cog-wheel, wheel, or other gearing attached thereto. This board, plate, or other support is mounted upon a foundation carrying the clock or timepiece in such a manner as to be capable of movement relative to the clock or timepiece, so that the mechanism of each dial or face can be brought into contact with the cog-wheel, wheel, or other gear attached to the clock or timepiece, so that the clock or timepiece when going will move the hand or hands or other index of the particular dial or face so brought into contact therewith; or, equivalently, I may adapt the various dials to slide or move upon their support relatively to the clock, so as to engage with and be disengaged from the gearing of the clock at will. To each main dial or face I in some cases provide a supplemental dial or face with the necessary gearing to indicate hours and also another supplemental dial or face to indicate seconds or to otherwise show that the mechanism of that particular main dial or face is being worked by the clock or timepiece.

The board, plate, or other support carrying the dials or faces may, if desired, be adapted to fall down out of the way of the clock or timepiece in order to obtain access to the same.

In order that my invention may be the bet-- ter understood, I will now proceed to describe the same in relation to the drawings hereunto annexed, reference being had to the letters marked thereon, like letters referring to like parts in the various figures.

Figure 1 is a front elevation of one form of my invention. Fig. 2 is a rear elevation of the vertical support for the dials. Fig. $3 is a side elevation of the complete device. Fig. 4 is a front elevation of the vertical support for the dials, thelatterbeing removed. Fig. 5 is a rear elevation of the clock with the vertical support removed. Fig. 6 is a front elevation of a modified form of my device. Fig. 7 is a back elevation of the same. Fig.8 is a detail view of the sliding sleeve carrying the indicating-dial and gear-wheels. Fig. 9 is a sectionalview ofthe same. Figs. 10 and 11 are further modified arrangements of gearing.

Referring to the form of device shown in Figs. 1 to 5, it will be seen that an ordinary clock A is attached to an angular supportB, to which is hinged the vertical board 0. This board is adapted to slide laterally a small dis tance upon its hiugepivot a. This is shown in Fig. The arbor of the minute-hand of the clock carries a cog-wheel D, the arbor be ing supported by a standard E, carried by the angular support B. The board C carries two cog-wheels F F, which gear with cog-wheels, G G, which are connected to the index-fingers H II of the dials J J, which are mounted upon the front face of the board A small dial K, with gear-whee1 L, is provided to each dial .I and operated by the cog-wheel Gto indicate the hours or the number of times the large hand has been around the dial. An.-

othersmall dial, with index-linger M, is also provid ed operated through the wheel by the wheel F to indicate the fact that the particular indexfinger desired is working. The board 0 can be folded down backward in order to obtain access to the back of the clock, and when in the vertical position is maintained in place by the jamming-screw O, which passes through the board and engages in the standard It. It will be seen that when the board C is slid transversely relative to the clock in one direction or the other one or other of the wheels F engage with the cogwheel D of the clock and the index-linger of the dial is operated. In Fig. 10 I show an equivalent arrangement in which the transverse rectilineal motion is substituted by an oscillating motion, the supporting-lever C, carrying the dials .I J and their gearing, being pivoted on the clock at the point P, so that either one or other dial can be put into motion, according to the side to which the lever C is tilted, in an equivalent manner to that hereinbefore described.

In Figs. (3 and 7 the clock is supported in the center of a cruciform frame, and each dial J and its gearing is mounted upon a sleeve R,

adapted to slide upon one of the radiating arms of the frame, so as to be moved rclatively to the clock with great facility. It will be seen from Fig. 7 that the four upper dials are disengaged from and the two lower dials are engaged with the cog-wheel D of the clock A. I provide memoranduni-tablets S upon the frame adjacent to the dials .I

which may have reference to the particular dial adjacent to it. The sleeve It is provided with a spring-tongue having a projection U, which is adapted to engage into either one of the holes V in the arms of the frame, so as to maintain the wheels into orout ol engagement, as circumstances require. Six separate and independent operations can be timed by this arrangement.

It is obvious that the devices as illustrated in Figs. 1, 2, 3, 4c, and 10 can be made with the supplemental dials facing in the opposite direction to the main dial, in which case the cog-wheels F would not be necessary, the wheels G and D gearing direct into one auother. This arrangement is clearly seen in Fig. 11. This would considerably lessen the amount of mechanism and the cost of manufaeture.

when it is not necessary that the true time This device is applicable for use i 1' by the clock or timepiece should be known at a glance. In the devices illustrated in Figs. 10 and 11 I lit retaining devices, such 3 as springtongues T, to maintain the desired ;dial and gearing in engagement with the i clock.

It is obvious that every one of the devices can be fitted with hour-hand arrange ments similar to that shown in Figs. 1 and 2. Further, by centrally dividing the board 0 vertically,as indicated by dotted line 1 2, Figs. 1, 2, and 4, each dial can be put into and taken out of action independently of the other according to the relative position of the dialsupport with the timing device substantially as described.

2. In a time-indicating device, the combination with a timing mechanism having an exposed gear-wheel, of a support movablyconnected with the timing mechanism, and two independent time-indicating trains carried on said support and having gear-wheels adapted to engage opposite sides of the exposed gear- 7 wheel of the timing mechanism, whereby J, upon which any given fact can be recorded either one or the other of said time-indicating trains can be operatively connected with said timing mechanism,substautially as described.

Ina time-indicating device, the combination with a time-indicating mechanism having an exposed gear-wheel, of a support on which said mechanism is mounted, a second support hinged to' the former, and movable laterally on its hinge-pintles, and one or more tin'le-indicating trains carried on said second support and adapted to be engaged and disengaged with said gear-wheel by the lateral movement of the support, substantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.

HENRY KING.
